A REVIEW ON MAGNETIC ABRASIVE MACHINING

Abstract

The magnetic abrasive machining is a machining method based on the use of the magnetic field to generate a flexible abrasive brush from abrasive and/or ferromagnetic particles. The possibility of obtaining low values for the Ra surface roughness parameter led to the use of this machining method, especially as an abrasive finishing method. Over the time, various versions of machining techniques were proposed and some of them were in detail investigated and applied in industry. When the problem of selection or application of a certain magnetic abrasive machining technique is formulated, information concerning the magnetic abrasive machining methods and techniques and their characteristics could be necessary. The documentary research activity allowed to the authors of this paper elaboration of a review on the magnetic abrasive machining/finishing, by taking into considerations information found in the accessible specialty literature. As a result, a synthetic presentation concerning some machining/finishing magnetic abrasive techniques, principles of this machining method, its applications and major research areas was elaborated.
